Fatigue Strengthening of Metallic Bridges using Carbon Fibre Reinforced Polymer System. A large number of metallic structures such as bridges, offshore platforms and large mining equipment are aging. Retrofitting such structures is becoming increasingly important in the 21st century. Using an advanced material, Carbon Fibre Reinforced Polymer (CFRP), to strengthen metallic structures is very promising. This project aims to develop reliable CFRP strengthening systems for aging metallic bridges. I ....Fatigue Strengthening of Metallic Bridges using Carbon Fibre Reinforced Polymer System. A large number of metallic structures such as bridges, offshore platforms and large mining equipment are aging. Retrofitting such structures is becoming increasingly important in the 21st century. Using an advanced material, Carbon Fibre Reinforced Polymer (CFRP), to strengthen metallic structures is very promising. This project aims to develop reliable CFRP strengthening systems for aging metallic bridges. It aims to make a breakthrough in understanding of the fatigue crack propagation in CFRP-metal composite system under combined loading. It intends also to produce practical guidelines for engineers to strengthen aging metallic bridges.Read moreRead less
Erosion of embankment dams and dam spillways. In excess of $250M is spent annually to maintain, upgrade, improve safety and monitor performance of Australian dams. Improved methods for assessing both spillway and internal erosion, the cause of 50 per cent of embankment dam failures and incidents requiring repairs, will be developed, maximising dam safety and minimising maintenance expenditure.
Development of advanced deterioration model for the design of stabilised pavement bases. The Australian road network is a lifeline infrastructure that underpins the nation's living standards and economy. Much of these roads have deteriorated and require rehabilitation to get a new lease of life. This project intends to develop advanced methods to extend the lives of these pavements using in-situ recycling of old pavement materials.
Minimisation of damage to residential structures due to ground movement. In Australia some 150,000 new houses are built every year with a total value of approximately $40 billion; making it one of the most significant industries affecting consumers and industries. With a quadrupling of the cost of building new houses in the last 20 years, an increase in the levels of expectations of owners, a high rate of reported damage in new and existing houses, and predications of worsening conditions under ....Minimisation of damage to residential structures due to ground movement. In Australia some 150,000 new houses are built every year with a total value of approximately $40 billion; making it one of the most significant industries affecting consumers and industries. With a quadrupling of the cost of building new houses in the last 20 years, an increase in the levels of expectations of owners, a high rate of reported damage in new and existing houses, and predications of worsening conditions under climate change scenarios; there is an urgent need to evaluate the causes of damage. The outcomes from this project will assist in minimising damage to houses from ground movement and in adopting new performance-based design methods for new homes to better match owner expectations. This will lead to cost effective and innovative solutions to meet adverse conditions.Read moreRead less
Cementitious gel: the missing link in understanding the ageing of built infrastructure. Exposure of built reinforced concrete infrastructure to coastal environments causes premature ageing, unplanned remediation and reduced safety. Enhanced forecasting, achieved by advanced methods, including Helium Ion Microscopy and modeling interactions between cement gel, chloride and water, will deliver proactive management of ageing assets.
Infrastructure project delivery: a life cycle evaluation model for public private partnerships. Governments continue to embrace public-private partnerships so as to obtain value for money and provide financial accountability to taxpayers. This project will determine the most appropriate way to engage the private sector in infrastructure delivery and develop a dynamic life cycle evaluation model to ensure projects are delivered effectively and efficiently.
A novel method for controlling microbial concrete corrosion in sewers. This project plans to use a newly discovered, low-cost and environmental benign antimicrobial agent to develop an innovative technology to control the development of corrosion-inducing sewer biofilms. Concrete sewer corrosion is a long-standing and costly problem for the water industry. Microbial hydrogen sulfide oxidation on concrete surfaces plays a critical role. The technology will be designed to prevent corrosion of new ....A novel method for controlling microbial concrete corrosion in sewers. This project plans to use a newly discovered, low-cost and environmental benign antimicrobial agent to develop an innovative technology to control the development of corrosion-inducing sewer biofilms. Concrete sewer corrosion is a long-standing and costly problem for the water industry. Microbial hydrogen sulfide oxidation on concrete surfaces plays a critical role. The technology will be designed to prevent corrosion of new concrete sewers by adding a precursor chemical into the cement, or to slow down the corrosion of existing sewers by infrequently (once every one to few years) spraying the precursor chemical directly onto the concrete surface. Potentially, the project will substantially reduce sewer corrosion.Read moreRead less
Planning and managing road transport systems for extreme events through spatial enablement. Transport infrastructure is one of the seven types of nationally significant critical infrastructure identified federally to ensure the continuity of essential services in the face of extreme events including terrorist attacks and natural disasters.

Transport infrastructure is one of the seven types of nationally significant critical infrastructure identified federally to ensure the continuity of essential services in the face of extreme events including terrorist attacks and natural disasters. This project aims to provide tools for determining the most cost efficient schedule of preventative strengthening works for road networks for reducing the disruption and recovery costs after extreme events. The project aims to develop a novel platform for increasing the resilience of road networks by blending transport resilience modelling and structural health vulnerability analysis of road infrastructure into one integrated spatially enabled road transport planning system.Read moreRead less

Funder
Australian Research Council
Funding Amount
$500,000.00
Summary
Integrated command and control facility for large-scale critical infrastructure management. This is a test bed facility for achieving sustainable operation of Australia's critical infrastructure, particularly at airports. The facility will enable an integrated and coordinated strategy to increase operational resilience while not losing sight of the complex nature and dynamic requirements of critical infrastructure management.
Greening procurement of infrastructure construction: optimising mass-haul operations to reduce greenhouse gas emissions. This project will develop and prototype tools to reduce the high environmental impact of mass haul operations in road and rail infrastructure projects. Both contractors and clients need practical methods for calculating, optimising and procuring optimal solutions, because mass haul is one of the few areas where a contractor can reduce carbon dioxide impact.
